Custom Carbide Punch Mold Components (45–75 HRC) | High-Performance Tooling for Tablet Press Dies

EXECUTIVE SUMMARY

Optimizing Powder Compaction with Micron-Precision Carbide Excellence

In the world of high-speed tablet compression and powder metallurgy, the performance of your punch defines your uptime. Senlan Precision manufactures custom Tungsten Carbide Punches specifically designed for tablet press systems, ranging from 45 to 75 HRC. We solve common industry failures such as premature chipping and material sticking by utilizing premium sub-micron grain carbide and advanced geometry control.

ADDRESSING CRITICAL MANUFACTURING PAIN POINTS

1. Eliminating Micro-Chipping & Fractures

• The Challenge: Incorrect carbide grades lead to edge embrittlement, causing punches to snap under high compression forces.

• Our Solution: We select the optimal Tungsten Carbide grade based on your application—balancing Cobalt content to maximize Compressive Strength while maintaining necessary Fracture Toughness.

2. Preventing Material Sticking (Ra < 0.05 Mirror Finish)

• The Challenge: Microscopic grinding marks on the punch face lead to "picking and sticking," requiring frequent cleaning stops.

• Our Solution: Our multi-stage diamond polishing process achieves a Super-Mirror Finish (Ra < 0.05μm). This ultra-smooth surface reduces friction and adhesion, improving tablet aesthetics and extending tool life.

3. Dynamic Precision & Concentricity Control

• The Challenge: Poor concentricity leads to uneven wear on the die and catastrophic machine vibration.

• Our Solution: Utilizing Japanese Jig Grinding and CNC OD grinding, we maintain Total Indicator Reading (TIR) within 0.002mm. Our "One-Setting" machining philosophy ensures all functional axes are perfectly aligned.

TECHNICAL SPECIFICATIONS & CAPABILITIES

CORE APPLICATIONS

• Pharmaceutical Tablet Press: Standard and complex-shaped pills (EU/TSM standards).

• Battery & Energy: Compressing lithium-ion powder and fuel cell components.

• Powder Metallurgy: Precision gears, bearings, and high-density industrial parts.

• Nutraceutical Packaging: High-volume vitamin and supplement production.

THE STRATEGIC ADVANTAGE OF SENLAN PRECISION

• Failure Analysis DFM: We review your punch tip geometry to identify stress concentration points before manufacturing begins.

• Sub-Micron Grain Purity: We exclusively use virgin carbide powders—no recycled scrap—ensuring consistent density.

• Advanced Metrology: Every batch is verified using Keyence Image Measuring Systems and digital hardness testers.

• Stress-Free Grinding: Our "cool-grinding" technique prevents thermal micro-cracking, the primary cause of carbide tool failure.

• Secure Global Logistics: Components are vacuum-sealed and housed in individual high-impact cases.

FAQ - TECHNICAL SUPPORT

Q: How do you ensure the Carbide Punch won't snap under high pressure?

A: We perform rigorous structural integrity checks and select carbide grades with high Transverse Rupture Strength (TRS). We also advise on the "Hardness vs. Toughness" balance for your specific tonnage.

Q: Can you match the precision of European OEM tooling?

A: Absolutely. Our facility utilizes MAKINO and HARDINGE platforms, allowing us to hit sub-micron tolerances identical to original equipment manufacturers.

Q: Do you support "Mixed-Hardness" orders for complex die sets?

A: Yes. We can manufacture the punch tip, body, and die with different carbide grades to optimize the wear-map of your entire assembly.
